Der Decoden Workshop bietet dir die Möglichkeit, in eine verspielte und kreative Welt einzutauchen und deine eigenen Decoden-Charms und Accessoires zu gestalten. Decoden ist eine dekorative Technik, bei der mit einer cremigen Leimmasse, Farben und süßen Charms gearbeitet wird. Dabei entstehen einzigartige Designs, die sowohl kreativ als auch individuell sind. Dieser Workshop eignet sich perfekt für alle, die etwas Neues ausprobieren und mit wenig Aufwand tolle Ergebnisse erzielen möchten. Im Decoden Workshop kannst du verschiedene Gegenstände nach deinem eigenen Stil gestalten. Zur Auswahl Bilderrahmen Etuis Handspiegel & Tischspiegel Schmuckkästchen Haarklammer Du entscheidest selbst, welches Objekt du dekorieren möchtest und wie verspielt, farbenfroh oder minimalistisch dein Design ausfallen soll. Jedes Werk ist ein Unikat und spiegelt deine persönliche Kreativität wider. Pro Gegenstand benötigst du etwa 15 bis 30 Minuten, je nach Detailgrad und Design. Dadurch eignet sich der Workshop sowohl für kurze kreative Pausen als auch für längere Bastelzeiten. Du kannst auch mehrere Objekte nacheinander gestalten, wenn du Lust hast, verschiedene Designs auszuprobieren. Der Preis startet ab 29 CHF pro Gegenstand. Im Preis enthalten sind eine Farbe und 20 Charms. Alle Materialien stehen für dich bereit, sodass du nichts mitbringen musst. Du kannst direkt loslegen und dich ganz auf das kreative Arbeiten konzentrieren. Wenn du zusätzliche Farben oder Charms verwenden möchtest, kannst du diese flexibel ergänzen. Auch Anfänger\*innen sind herzlich willkommen. Du brauchst keinerlei Vorkenntnisse, um am Decoden Workshop teilzunehmen. Ich erkläre dir Schritt für Schritt, wie die Technik funktioniert, wie du den Leim richtig aufträgst und wie du deine Charms platzierst, damit dein Design harmonisch wirkt. Während des gesamten Workshops stehe ich dir mit Tipps und Unterstützung zur Seite.

Manga zeichnen wirkt auf den ersten Blick oft kompliziert und einschüchternd. Die ausdrucksstarken Augen, besonderen Proportionen und dynamischen Figuren lassen viele glauben, dass man dafür jahrelange Erfahrung braucht. Doch genau hier setzt dieser Manga-Zeichenworkshop an: Manga zu zeichnen ist viel zugänglicher, als viele denken – wenn man die richtigen Grundlagen kennt und Schritt für Schritt angeleitet wird. In diesem Workshop lernen Erwachsene auf verständliche und entspannte Weise die wichtigsten Techniken des Manga-Zeichnens kennen. Der Kurs ist so aufgebaut, dass auch absolute Anfänger\*innen problemlos einsteigen können. Ziel ist es, Hemmungen abzubauen, neue kreative Impulse zu geben und den eigenen Zeichenstil zu entdecken. Alle benötigten Materialien sind im Kurs inklusive. Zeichenpapier, Stifte und weitere Utensilien stehen vor Ort zur Verfügung, sodass du einfach kommen und direkt loslegen kannst. Der Fokus liegt nicht auf Perfektion, sondern auf dem Freude am Zeichnen, Ausprobieren und Weiterentwickeln. Am Ende des Workshops nimmst du nicht nur deine eigenen Zeichnungen mit nach Hause, sondern auch neue Techniken und mehr Sicherheit im Zeichnen.

Im Punch Needle Workshop verwandelst du einfache Fäden in ein einzigartiges Kunstwerk. Punch Needle ist eine moderne und zugleich entspannende Sticktechnik, bei der mit einer speziellen Nadel Schlaufen in den Stoff gestochen werden. So entstehen strukturierte, weiche Oberflächen und ausdrucksstarke Muster. Der Workshop ist ideal, um Punch Needle kennenzulernen, kreativ abzuschalten oder in kurzer Zeit etwas Schönes mit den eigenen Händen zu erschaffen – ganz ohne Vorkenntnisse. Zu Beginn des Workshops erhältst du eine kurze Einführung in die Grundlagen der Punch-Needle-Technik. Ich zeige dir Schritt für Schritt, wie die Nadel richtig verwendet wird, wie du den Faden führst und gleichmäßige Schlaufen erzeugst. Du lernst, worauf du achten musst, damit dein Motiv sauber und stabil wird. Die ruhige, gleichmäßige Bewegung macht Punch Needle besonders entspannend und perfekt für eine kreative Auszeit vom Alltag. Im Workshop kannst du zwischen zwei kreativen Optionen wählen: Option 1 – Motiv sticken (29 CHF) Du wählst ein bestehendes (oder eigenes) Motiv und stickst dieses ohne Hintergrund. Diese Option ist ideal für Einsteiger\*innen oder alle, die Punch Needle unkompliziert ausprobieren möchten. Der Fokus liegt ganz auf der Technik und dem Motiv selbst. Hier kannst du dein Werk in eine Untertasse verwandeln. Option 2 – Motiv mit Hintergrund (35 CHF) Hier stickst du dein Motiv inklusive Hintergrund. Dadurch erhält dein Werk mehr Tiefe und eine besonders schöne, flächige Struktur. Diese Option eignet sich für alle, die ihr Kunstwerk etwas aufwendiger gestalten möchten. Hier kannst du dein Werk auch in eine Untertasse verwandeln, oder als Deko aufhängen. Die maximale Workshopdauer beträgt bis zu 1 Stunde. Je nach Tempo und Design kannst du dein Werk in dieser Zeit fertigstellen oder einen grossen Teil davon umsetzen. Während des gesamten Workshops begleite ich dich persönlich, gebe Tipps und unterstütze dich bei Fragen oder Unsicherheiten. Alles darf, nichts muss – wichtig ist, dass du Freude am Prozess hast. Alle Materialien sind inklusive. Du arbeitest mit hochwertigen Garnen in verschiedenen Farben, Stoff, Rahmen und Punch Needle. Du musst nichts mitbringen – ausser Lust auf Kreativität. Dein gesticktes Werk kannst du am Ende direkt mit nach Hause nehmen, sei es als Dekoration, Geschenk oder persönliches Erinnerungsstück. Wenn du Lust hast, etwas Neues zu entdecken, kreativ zu entspannen und in kurzer Zeit ein eigenes Kunstwerk zu gestalten, ist dieser Punch Needle Workshop genau das Richtige für dich. 🧶✨

**🚀 JavaScript Luzern Meetup** Hey everyone! We're planning for another evening of frontend goodness. 📋 What's on the agenda? **Coding the coder: how coding agents work - Hugo Sousa** You’ve probably already tried or are using on a daily basis a coding agent, such as Claude Code, Codex, OpenCode, Pi, etc. But perhaps you’re not aware of how they work. What is a coding agent? What does it take to build one? In this talk I’ll dig into the internals of coding agents and what it takes to build a minimal one. **The Browser Is Your Framework - Mateusz Halada** Let’s explore how modern web applications can be built directly on the platform using HTML, CSS, JavaScript, and browser APIs - without defaulting to heavy frameworks. Through a live demo, we’ll recreate common UI patterns and show what frameworks actually abstract under the hood. We’ll also demystify concepts like SPA, SSR, and CSR to understand where they truly come from. The goal isn’t to replace frameworks, but to give you the clarity to choose them intentionally—and know when you don’t need them. **Coding Atrophy: What Software Engineers Can Learn From Aviation - Maximilian Walterskirchen** Aviation spent 30 years figuring out that automated cockpits were atrophying pilot skills. The data on AI coding tools is starting to look uncomfortably similar. A talk on what aviation figured out, what the research shows, and the bug that made me realize my own skills had gone soft. 🎤 Call for Speakers! We still have open slots and would love to hear from you! If you've been working on something interesting — whether it's AI-related or any other JavaScript/CSS topic — reach out and share it with the community. Not sure what to talk about? We can help suggest a topic based on your interests. First-time speakers are absolutely welcome! Food and drinks are on us. A big thank you to [CSS](https://www.css.ch/) for providing the location! See you there! 🙌

Welcome to the Competitive Play Session. This session takes place every Saturday from 10:45 to 12:15 at the Yonex Badminton Hall Hardbrücke.

Players are accepted into the session based on skill suitability. This session is for experienced players looking for quality games. Play is focused on doubles with a competitive mindset and consistent rallies. You should be comfortable smashing, return smashes and keeping up a moderate tempo throughout the session. New players and those who are new to badminton are welcome to join the PM Session (Open Level Play). Payment can be made via TWINT after the session.

Web Zurich presents inspiring talks all about the web. Join us for the Mai 2026 meetup! We will have three talks as well as chit-chat and drinks. Whatapp: [https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK](https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK) Website: [https://webzurich.ch](https://webzurich.ch) 18:30 \~ 19:00 Arrival time with drinks, chat 19:00 \~ 19:10 Welcome and introduction 19:10 \~ 19:30 *Alex Suzuki* **Monetizing JavaScript: Building Profitable Products as a Solo Developer** Lessons learned from building and launching a commercial JavaScript library as a solo developer. 19:30 \~ 19:50 *Hugo Sousa* **Ten times tea** I'm building a programming language. When I got to the frontend, I ran into a problem: React's mental model is elegant, but the mental model is at odds with the code. Hooks, effects, and render passes create a runtime that bears little resemblance to the code we write. The Elm programming language works differently and its architecture (TEA = The Elm Architecture) has been adopted by other tools over the years. So I copied it as well. My language embeds TEA at the language level, not as a library. This unlocks time-travel debugging, reproducible application state and serializable bug reports that include the entire program state. This talk covers the quick introduction of my language, TEA, why TEA is the right fit and what becomes possible when the architecture is baked into the language itself. 19:50 \~ 20:10 *Marco Gähler* **Software testing** Many old software projects don't have any tests - if the code works, why should you bother with tests? Well, you really should bother, because code changes all the time. During development, you keep adding new features which at times requires large scale modifications of the code that will inevitably alter existing functionality. And in existing projects, one still has to make updates once in a while, for example for security patches. These things will always break existing functionality and tests are the only remedy against this issue. In this talk, we will look at the basic idea of tests, how to implement them, what issues to look out for and how you can test pretty much any piece of code if your code base is well structured. 20:10 onward More drinks & chat We look forward to see you there!

Model Context Protocol (MCP) is emerging as a standard way for AI models to securely interact with external tools and systems. This session provides a practical deep dive into MCP architecture, core concepts, and real-world integration patterns. We will explore how MCP enables structured tool calling, improves interoperability, and simplifies AI integration in existing applications. The talk will include examples of connecting AI models with APIs, databases, and enterprise systems, with a focus on how developers can adopt MCP in Java-based environments. **Note**: This is a hybrid in-person/online event. Food and social for those in the OCI training room starts at 6:00pm. Presentation starts at 6:30pm for those online and in the training room.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** Like it or not, AI agents are now capable of turning a quickly written paragraph of requirements into a pull request that is ready to be integrated into real-world production applications and it's now our responsibility to make sure AI doesn't go rogue and take down prod - or corrupt our data by misunderstanding the requirements or our existing schemas. In this session we'll explore strategies to protect our codebases through unit and integration testing, documentation, and code review along with additional ways of providing context and guard rails to our AI agents as they carry out the work we've assigned them to do. By the time we're done, you'll have a firm grasp of the problem and understand some helpful options for protecting your codebase from vibe coding mishaps getting YOLOed into prod. **YouTube Link** TBD
